Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0033] Please refer to Figures 1 to 6 , Figure 1 Figure 1 is the appearance diagram of the electric stimulation therapeutic instrument provided in one specific embodiment of the utility model; Figure 2 Figure 2 is the appearance diagram of the electric stimulation therapeutic instrument provided in one specific embodiment of the utility model from another perspective; Figure 3 Figure 3 is an exploded view of the electric stimulation therapeutic instrument; Figure 4 Figure 1 is a schematic diagram of the connection between the mounting frame and the upper protective shell in the electric stimulation therapeutic instrument; Figure 5 Figure 2 is a schematic diagram of the connection between the mounting frame and the upper protective shell; Figure 6 Figure 3 is a schematic diagram of the connection between the fixing plate and the display screen.

[0034] In a specific embodiment, the electric stimulation therapeutic instrument comprises an upper protective shell 4 and a lower protective shell 1 which are connected to each other and form a cavity inside, a circuit board 2 and a storage battery 3 which are connected in the cavity, an installation frame 8 which is detachably connected to the outer surface of the upper protective shell 4, a mounting groove is formed on the side of the installation frame 8 away from the upper protective shell 4, a fixing plate 9 is connected in the mounting groove, a recess is formed on the side of the fixing plate 9 away from the upper protective shell 4, an elastic device is connected to the inner wall of the recess, the elastic force of the elastic device is perpendicular to the inner wall of the recess, and a display screen 13 is installed in the recess and is in pressure connection with the elastic device.

[0035] In the above structure, the electric stimulation therapeutic instrument comprises the upper protective shell 4, the lower protective shell 1, the circuit board 2, the storage battery 3, the installation frame 8, the fixing plate 9 and the display screen 13, the upper protective shell 4 and the lower protective shell 1 are connected by snap-fit or screw connection, the cavity is formed between the upper protective shell 4 and the lower protective shell 1, and the circuit board 2 and the storage battery 3 are installed in the cavity. By means of the cooperation of the lower protective shell 1 and the upper protective shell 4, the circuit board 2 and the storage battery 3 inside can be installed and fixed, and can also be protected. Preferably, a module for supporting and fixing the circuit board 2 is arranged between the upper protective shell 4 and the lower protective shell 1, so as to ensure the stability of the circuit board 2.

[0036] The fixing plate 9 is connected in the mounting groove of the installation frame 8, and the mounting groove is on the side away from the upper protective shell 4. The display screen 13 is installed in the recess of the fixing plate 9, and the recess is on the side away from the upper protective shell 4. The installation frame 8, the fixing plate 9 and the display screen 13 form an integral whole. The outer surface of the upper protective shell 4 is connected to the installation frame 8 in a detachable manner, for example, by using buckles. The integral whole is installed on the outer surface of the upper protective shell 4 through the installation frame 8. Specifically, the buckles between the installation frame 8 and the upper protective shell 4 are fixed relative to each other, the upper protective shell 4 and the installation frame 8 are connected and fixed, and the connection between the upper protective shell 4 and the display screen 13 is realized. When the display screen 13 needs to be replaced, the buckles are opened, and the installation frame 8 together with the fixing plate 9 and the display screen 13 can be conveniently detached, thereby reducing the operation difficulty. When the display screen 13 is damaged, the integral whole can be more conveniently detached and replaced, thereby improving the practicability of the electric stimulation therapeutic instrument.

[0037] The addition of the elastic device provides additional support, buffering and protection for the display screen 13. The elastic device is connected to the inner wall of the recess of the fixing plate 9, and the elastic force of the elastic device is perpendicular to the inner wall of the recess, which means that the direction of the elastic force is perpendicular to the side wall of the display screen 13. The side wall of the display screen 13 abuts against the surface of the elastic device, and the two are in pressure connection with each other.

[0038] The elastic device supports the periphery of the display screen 13, provides buffering and protection. When the device is subjected to a falling impact, the elastic device can absorb and offset the impact force, reducing the direct impact of the impact on the display screen 13, thereby improving the safety of the device. In the absence of force, the elastic device can ensure the stability of the display screen 13 and will not affect the normal use of the display screen 13. This design takes into account various situations that the display screen 13 may encounter in actual use, such as falling, impact, etc., and effectively reduces the damage that these situations may cause to the display screen 13 through the buffering effect of the elastic device.

[0039] On the basis of the above various embodiments, each side wall of the groove has a plurality of elastic devices, each elastic device comprising two oppositely directed spring pieces 12, the ends of the two spring pieces 12 having a gap and being arranged in a spread-eagle shape.

[0040] In one embodiment, a plurality of elastic devices are provided on the inner wall of the groove of the fixed plate 9, which provide support, buffering and protection for the display screen 13. Through the plurality of elastic devices, the force received by the display screen 13 can be dispersed to multiple points, thereby reducing stress concentration at a single point and improving the stability and durability of the structure.

[0041] Each elastic device comprises two oppositely directed spring pieces 12, each set of spring pieces 12 being arranged in a spread-eagle shape, which helps to provide uniform support force on both sides of the display screen 13, ensuring that the display screen 13 can evenly disperse the impact force when subjected to impact, reducing damage to the display screen 13.

[0042] The ends of each set of spring pieces 12 have a gap to avoid interference between the two spring pieces 12, allowing the spring pieces 12 to have a certain expansion space when subjected to force, which helps to absorb the impact force, while maintaining the stability of the display screen 13 when not subjected to force.

[0043] It should be noted that the elastic coefficient of the elastic device is sufficient to achieve the support, buffering, protection and stability functions described above. The elastic device can be a spring, spring piece 12, etc. The elastic coefficient, i.e. stiffness, of the elastic device is one of its key parameters, which determines the degree of deformation of the elastic device when subjected to force. Selecting an appropriate elastic coefficient can ensure that the elastic device can effectively absorb and offset the impact force when subjected to a falling impact, while not affecting the display screen 13 during normal use.

[0044] On the basis of the above various embodiments, the inner wall of the groove is provided with a slot, the connecting portion of the spring piece 12 is inserted into the slot, and the spring piece 12 is inserted along the circumferential direction of the groove.

[0045] In a specific embodiment, the position of the spring sheet 12 can be accurately positioned by providing a slot on the inner wall of the groove. The connecting part of the spring sheet 12 is inserted into the slot, simplifying the installation process and making the installation of the elastic device more convenient and efficient. When the elastic device needs to be replaced or maintained, the spring sheet 12 can be easily disassembled and reinstalled. The slot provides a stable fixing point for the spring sheet 12, reducing the movement or rotation of the spring sheet 12 under stress, thereby improving the stability of the entire structure. The spring sheet 12 is inserted along the circumferential direction of the groove. This design allows the spring sheet 12 to have a certain space for movement when impacted, thereby better absorbing and dispersing impact forces.

[0046] Preferably, the depth of the spring sheet 12 inserted into the slot is adjustable, allowing the tension of the spring sheet 12 to be adjusted as needed to accommodate display screens 13 of different sizes or thicknesses.

[0047] Based on the above-mentioned various specific embodiments, the initial height of the end of the spring sheet 12 is equal, and the end of the spring sheet 12 is provided with an arc-shaped hem that contacts the side wall of the display screen 13.

[0048] In a specific embodiment, the initial height of the end of the spring sheet 12 is equal, and the deformation of the two spring sheets 12 when supporting the display screen 13 is equal, and the supporting force is equal, which helps to maintain the stability of the display screen 13 when not under stress and does not affect the normal use of the display screen 13. The stress conditions of the two spring sheets 12 are the same, and the durability is comparable.

[0049] The side wall of the display screen 13 contacts the arc-shaped hem, which is not easy to scratch the display screen 13, and can ensure that the contact between the spring sheet 12 and the side wall of the display screen 13 is more uniform, thereby avoiding stress concentration and reducing damage to the display screen 13. The arc-shaped hem increases the contact area between the spring sheet 12 and the side wall of the display screen 13, thereby improving the buffering effect and better absorbing and dispersing impact forces. The hem design can effectively reduce the friction between the spring sheet 12 and the side wall of the display screen 13, reduce wear and tear, and improve the durability of the product.

[0050] In the above-mentioned embodiments, by adding an arc-shaped hem to the end of the spring sheet 12, not only the safety and stability of the display screen 13 are improved, but also the aesthetic appearance and durability of the product are improved.

[0051] Based on the above-mentioned various specific embodiments, the spring sheet 12 has an arc-shaped slot, and the side wall of the display screen 13 is provided with an arc-shaped protrusion that cooperates with the arc-shaped slot, and the arc-shaped protrusion is inserted into the arc-shaped slot.

[0052] In a specific embodiment, the arc-shaped clamping groove of the spring sheet 12 and the arc-shaped protrusion of the sidewall of the display screen 13 are clamped with each other, which can be semicircular or long strip-shaped. After correct installation, the arc-shaped protrusion can be automatically locked in the clamping groove due to the elasticity of the spring sheet 12, preventing the display screen 13 from being accidentally detached; it can ensure that the display screen 13 can be closely and stably matched with the fixing plate 9 during installation.

[0053] On the basis of the above various specific embodiments, the elastic devices on the inner walls of the grooves are distributed in axial symmetry, which can ensure that the display screen 13 is uniformly stressed during installation, providing uniform support and buffering, and avoiding damage caused by uneven stress.

[0054] On the basis of the above various specific embodiments, the elastic devices on each inner wall of the grooves are equally spaced, which can provide uniform support and ensure the stability of the display screen 13 at each point.

[0055] On the basis of the above various specific embodiments, the back plate of the fixing plate 9 is provided with a buffer pad 16 on the side facing the grooves, and the back of the display screen 13 is in contact with the buffer pad 16.

[0056] In a specific embodiment, the provision of the buffer pad 16 can form a buffer protection under the display screen 13, and a small amplitude movable space can be formed when the user touches and presses, thereby reducing the damage to the display screen 13 caused by excessive impact.

[0057] On the basis of the above various specific embodiments, the outer surface of the upper protective shell 4 includes a connecting groove matched with the installation frame 8 and a key groove connected with the control button 7, and the installation frame 8 is connected with the upper protective shell 4 through the buckle and the bayonet.

[0058] In a specific embodiment, the connecting groove is a key part of the cooperation between the upper protective shell 4 and the installation frame 8, which is usually designed to accommodate the shape of the buckle. This design can ensure that the display screen 13 can be accurately positioned during installation, and the buckle can be firmly connected through elastic deformation. The size and shape of the connecting groove need to be accurately designed according to the size and shape of the buckle to ensure that they can perfectly match.

[0059] The key groove is used to connect the control button 7, which is usually located on the outer surface of the upper protective shell 4 and cooperates with the protruding part of the button. By the cooperation of the power button 6 installed on the outer side of the upper protective shell 4 and the control button 7 inside the upper protective shell 4, the control part on the circuit board 2 can be pressed, which is more convenient for the user to operate and control. The design of the key groove needs to consider the comfort and durability of the button operation, while ensuring that the button will not be displaced or detached during operation. The symmetry tolerance and dimensional accuracy of the key groove are crucial to ensure the stable connection of the button.

[0060] The mounting frame 8 and the upper protective shell 4 are connected by the buckle and the bayonet, which realizes quick assembly and disassembly, and ensures the stability and reliability of the connection. The buckle is usually designed to be elastically deformed, so that it can be inserted into the bayonet and locked in place, providing stable connection while allowing the user to easily disassemble the display screen 13 when needed.
